Sustainable electro-synthesis of esters

National University of Singapore chemists have discovered how acetate esters could be electro-synthesized from water and carbon monoxide in an environmentally sustainable way.

How did Earth avoid a Mars-like fate? Ancient rocks hold clues

Approximately 1,800 miles beneath our feet, swirling liquid iron in the Earth's outer core generates our planet's protective magnetic field. This magnetic field is invisible but is vital for life on Earth's surface because ...

Solar storm to hit Earth's magnetic field on July 21

Something is happening to the sun. One of the regions of the solar atmosphere currently exhibiting sunspots caught the attention of observatories on July 11, when there was a sudden increase in ultraviolet and X-ray brightness. ...

Cable bacteria: Electric marvels of microbial world

The emergence of multicellularity, requiring complex interactions between different groups of individual cells for metabolic and physiological benefits, is a great success in the history of biology. While multicellularity ...

A primary standard for measuring vacuum

A novel, quantum-based vacuum gauge system invented by researchers at the National Institute of Standards and Technology (NIST) has passed its first test to be a true primary standard—that is, intrinsically accurate without ...

Space weather will delay your trains

Fluctuations in space weather are disrupting train signals and causing significant delays. A project investigating the effect of solar storms on railway signals will be presented this week at the National Astronomy Meeting ...

A proof of odd-parity superconductivity

Superconductivity is a fascinating state of matter in which an electrical current can flow without any resistance. Usually, it can exist in two forms. One is destroyed easily with a magnetic field and has "even parity" (i.e., ...

Electric current

Electric current is the rate of flow of electric charge. The electric charge that flows is carried by, for example, mobile electrons in a conductor, ions in an electrolyte or both in a plasma.

The SI unit of electric current intensity is the ampere. Electric current is measured using an ammeter.
